Performance and reliability tools. PC owners will be able to choose to have Windows OneCare automatically carry out periodic maintenance tasks such as disk cleanup, hard-drive defragmentation and file repair. The service also will offer boot-time information and proactive support tools to help improve the customer experience.

Backup and restore capabilities. Windows OneCare will enable automated backup of files by category on CD and DVD, along with the option to back up all files on the system or only those that have changed since the last time the action was performed. If files are accidentally deleted or corrupted on the PC hard drive, the service is designed to restore saved versions or map them on a new PC.

Simple, integrated service experience. PC users will have one simple point of reference for checking the overall health of their system. Windows OneCare will automatically notify users of available updates or other recommended actions and enable users to easily act as needed. Otherwise, the service stays quiet and in the background.
